A deranged Upper West Side man who fatally stabbed his 70-year-old father in the neck last week claimed to cops that the father had tried to rape him when he was a child.

“He used to try to rape me when I was a kid,” cops say Julian Kurita, 30, told them in the hallway outside the bloodbath that was his 175 West 87th Street apartment.

“Am I going to bleed to death?” he asked paramedics. Kurita had slashed at his own wrists by the time cops responded to his 911 call reporting the murder.

Kurita’s police statements — which do not include any remarks by Kurita regarding his father — were released today as he pleaded not guilty to the murder. He remains held without bail in a jail ward at Bellevue Hospital.
